Write two solutions for the following equation 2x+3y=24.

SVETLANKA909090 [29]

Answer: (12, 0) and (0, 8)

Step-by-step explanation:

This equation is in standard form. We can sub in a number for x to solve for y and vice versa.

Let's sub in 0 for x.

$2x+3y=24\\2(0)+3y=24\\3y=24\\\frac{3y}{3} =\frac{24}{3} \\y=8$

When x is 0 y is 8 giving us the coordinate (0, 8).

Now lets sub in 0 for y

$2x+3(0)=24\\2x=24\\\frac{2x}{2} =\frac{24}{2} \\x=12$

When y is 0 x is 12 giving us the coordinate (12, 0)

From a group of 8 people, including George and Nina, 3 people are to be selected at random to work on a certain project. What is

cestrela7 [59]

Answer: $\frac{15}{56}$

Step-by-step explanation:

We have to select george but not nina with two other people

No. of ways selecting 2 two people knowing Geroge will be the third one is

$^6C_2$ (beacuse we have to exclude Nina)

And total no of ways of selecting 3 people out of 8 people is $^8C_3$

Therefore the required Probability is $\frac{^6C_{2}}{^8C_{3}}$

= $\frac{15}{56}$

PLEASE SIMPLIFY THESE

Pavel [41]

Answer:

a. 0.69x + 0.14

b. 5.67 - 30.48a

c. 1.1x - 3.01y

Step-by-step explanation:

a) 2.56x + 0.14 − 1.87x

To simplify this algebraic expression, you start by collecting like terms;

2.56x − 1.87x + 0.14

Then perform arithmetic operation

0.69x + 0.14

b) 7.32a + 2.1 (2.7 − 18a)

Here; first, the bracket must be opened

To open the bracket; each expression in the bracket is multiplied by 2.1. This leaves us with

7.32a + 2.1 * 2.7 − 2.1 * 18a

7.32a + 5.67 - 37.8a

Then, you collect like terms

7.32a - 37.8a + 5.67

Then perform arithmetic operation

-30.48a + 5.67

Rearrange

5.67 - 30.48a

c) 0.12x + 0.34y + 0.98x − 3.35y

Here, you start by collecting like terms

0.12x + 0.98x + 0.34y − 3.35y

Then perform arithmetic operation

1.1x - 3.01y
